What is redox reaction? When a magnesium ribbon burns in air with a dazzling flame and forms a white ash, is magnesium oxidised or reduced? Why?
i. The reaction in which one reactant gets oxidised and the other reactant gets reduced is called redox reaction. ii. When a magnesium ribbon burns in air with a dazzling flame...

The solubilities of carbonates decrease down the magnesium group due to a decrease in
(b) : The stability of the carbonates of the alkaline earth metals increases on moving down the group. The solubility of carbonate of metals in water is generally low. However...

The solubility of AgCl in water at 25^0 C is found to be 1.06*10^-5 moles per litre. Calculate the solubility product of AgCl at this temperature.
AgCl ionizes completely in the solution as AgCl ----> Ag+ +Cl— One mole of AgCl in the solution gives 1 mole of Ag+ ions and 1 mole of Cl—ions. Now as the...

How does the of Ionization Enthalpy of alkaline earth metals vary in comparison to alkali metals.
The alkaline earth metals have low ionization enthalpies due to fairly large size of the atoms. Since the atomic size increases down the group, their ionization enthalpy decreases The first...
